Systematic studies of the accuracy of the Penning trap mass spectrometer JYFLTRAP

Measurements to quantify the mass-dependent systematic effect and the residual uncertainty of the JYFLTRAP setup have been performed with carbon-cluster ions. The primary quantities reported in this work are a mass-dependent uncertainty of σ m ( r ) / r = ( 7.8 ± 0.3 × 10 - 10 / u ) × Δ m and a residual uncertainty of σ res ( r ) / r = 1.2 × 10 - 8 for the JYFLTRAP mass spectrometer. By restricting the mass difference between the reference ion and ion of interest to | m meas - m ref | ≤ 24 , the values for the mass-dependent effect and the corresponding residual uncertainty are σ m , lim ( r ) / r = ( 7.5 ± 0.4 × 10 - 10 / u ) × Δ m and σ res , lim ( r ) / r = 7.9 × 10 - 9 , respectively.
